Start a persistence service that uses Redis™ as the persistence provider. The service requires a connection name and an open port. Once the service is running, you can connect to the service using the connection name and create a cache.

ctrl = mps.cache.control('myRedisConnection','Redis','Port',4519);
start(ctrl)
c = mps.cache.connect('myCache', 'Connection', 'myRedisConnection');

Retain a few keys locally.

retain(c, {'keyOne','keyTwo'})

Add keys and values to the cache.

put(c,'keyOne',10,'keyTwo',20,'keyThree',30,'keyFour',[400 500],'keyFive',magic(5))

Count the number of keys-value pairs.

numTotal = length(c)
numRemote = length(c,'Remote')
numLocal = length(c,'Local')

numTotal =

  int64

   5

numRemote =

  int64

   3

numLocal =

  int64

   2

Since keyOne and keyTwo were retained before being written to the cache, they were never written to the persistence service. They are stored locally until flushed or purged to the persistence service.
